public Class IntNode

Overrides com.fasterxml.jackson.databind.JsonNode.asBoolean.

Doc from com.fasterxml.jackson.databind.JsonNode.asBoolean.

Method that will try to convert value of this node to a Java boolean. JSON booleans map naturally; integer numbers other than 0 map to true, and 0 maps to false and Strings 'true' and 'false' map to corresponding values.

If representation cannot be converted to a boolean value (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

@Override

Implements abstract com.fasterxml.jackson.databind.node.NumericNode.asText.

Doc from com.fasterxml.jackson.databind.JsonNode.asText.

Method that will return a valid String representation of the container value, if the node is a value node (method isValueNode returns true), otherwise empty String.

@Override

Implements abstract com.fasterxml.jackson.databind.node.ValueNode.asToken.

Implements com.fasterxml.jackson.core.TreeNode.asToken.

Doc from com.fasterxml.jackson.databind.node.BaseJsonNode.asToken.

Method that can be used for efficient type detection when using stream abstraction for traversing nodes. Will return the first JsonToken that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)

Returns:JsonToken

Doc from com.fasterxml.jackson.core.TreeNode.asToken.

JsonToken that is most closely associated with the node type

@Override

Implements abstract com.fasterxml.jackson.databind.node.NumericNode.bigIntegerValue.

Doc from com.fasterxml.jackson.databind.JsonNode.bigIntegerValue.

Returns integer value for this node (as BigInteger), if and only if this node is numeric (isNumber returns true). For other types returns BigInteger.ZERO.

Returns:BigInteger

BigInteger value this node contains, if numeric node; BigInteger.ZERO for non-number nodes.

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.node.NumericNode.canConvertToInt.

Doc from com.fasterxml.jackson.databind.JsonNode.canConvertToInt.

Method that can be used to check whether this node is a numeric node (isNumber would return true) AND its value fits within Java's 32-bit signed integer type, int. Note that floating-point numbers are convertible if the integral part fits without overflow (as per standard Java coercion rules)

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.node.NumericNode.canConvertToLong.

Doc from com.fasterxml.jackson.databind.JsonNode.canConvertToLong.

Method that can be used to check whether this node is a numeric node (isNumber would return true) AND its value fits within Java's 64-bit signed integer type, long. Note that floating-point numbers are convertible if the integral part fits without overflow (as per standard Java coercion rules)

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.node.NumericNode.decimalValue.

Doc from com.fasterxml.jackson.databind.JsonNode.decimalValue.

Returns floating point value for this node (as BigDecimal), if and only if this node is numeric (isNumber returns true). For other types returns BigDecimal.ZERO.

Returns:BigDecimal

BigDecimal value this node contains, if numeric node; BigDecimal.ZERO for non-number nodes.

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.node.NumericNode.doubleValue.

Doc from com.fasterxml.jackson.databind.JsonNode.doubleValue.

Returns 64-bit floating point (double) value for this node, if and only if this node is numeric (isNumber returns true). For other types returns 0.0. For integer values, conversion is done using coercion; this may result in overflows with BigInteger values.

Returns:double

64-bit double value this node contains, if any; 0.0 for non-number nodes.

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.JsonNode.equals.

Doc from com.fasterxml.jackson.databind.JsonNode.equals.

Equality for node objects is defined as full (deep) value equality. This means that it is possible to compare complete JSON trees for equality by comparing equality of root nodes.

Parameters

o:Object

Doc from java.lang.Object.equals.

the reference object with which to compare.

Returns:boolean

Doc from java.lang.Object.equals.

true if this object is the same as the obj argument; false otherwise.

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.floatValue.

Doc from com.fasterxml.jackson.databind.JsonNode.floatValue.

Returns 32-bit floating value for this node, if and only if this node is numeric (isNumber returns true). For other types returns 0.0. For integer values, conversion is done using coercion; this means that an overflow is possible for `long` values

Returns:float

32-bit float value this node contains, if any; 0.0 for non-number nodes.

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.node.BaseJsonNode.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns:int

a hash code value for this object

@Override

Implements abstract com.fasterxml.jackson.databind.node.NumericNode.intValue.

Doc from com.fasterxml.jackson.databind.JsonNode.intValue.

Returns integer value for this node, if and only if this node is numeric (isNumber returns true). For other types returns 0. For floating-point numbers, value is truncated using default Java coercion, similar to how cast from double to int operates.

Returns:int

Integer value this node contains, if any; 0 for non-number nodes.

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.isInt.

Doc from com.fasterxml.jackson.databind.JsonNode.isInt.

Method that can be used to check whether contained value is a number represented as Java int. Note, however, that even if this method returns false, it is possible that conversion would be possible from other numeric types -- to check if this is possible, use canConvertToInt() instead.

Returns:boolean

True if the value contained by this node is stored as Java int

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.isIntegralNumber.

Returns:boolean

Doc from com.fasterxml.jackson.databind.JsonNode.isIntegralNumber.

True if this node represents an integral (integer) numeric JSON value

@Override

Implements abstract com.fasterxml.jackson.databind.node.NumericNode.longValue.

Doc from com.fasterxml.jackson.databind.JsonNode.longValue.

Returns 64-bit long value for this node, if and only if this node is numeric (isNumber returns true). For other types returns 0. For floating-point numbers, value is truncated using default Java coercion, similar to how cast from double to long operates.

Returns:long

Long value this node contains, if any; 0 for non-number nodes.

Implements com.fasterxml.jackson.core.TreeNode.numberType.

Returns code that identifies type of underlying numeric value, if (and only if) node is a number node.

Returns:JsonParser.NumberType

Doc from com.fasterxml.jackson.core.TreeNode.numberType.

Type of number contained, if any; or null if node does not contain numeric value.

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.node.NumericNode.numberValue.

Doc from com.fasterxml.jackson.databind.JsonNode.numberValue.

Returns numeric value for this node, if and only if this node is numeric (isNumber returns true); otherwise returns null

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.shortValue.

Doc from com.fasterxml.jackson.databind.JsonNode.shortValue.

Returns 16-bit short value for this node, if and only if this node is numeric (isNumber returns true). For other types returns 0. For floating-point numbers, value is truncated using default Java coercion, similar to how cast from double to short operates.
