public final Class JrsMissing

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

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

JsonToken that is most closely associated with the node type

@Override

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

o:Object

the reference object with which to compare.

Returns:boolean

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

Implements abstract com.fasterxml.jackson.jr.stree.JrsValue.get.

Implements com.fasterxml.jackson.core.TreeNode.get.

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

Method for accessing value of the specified field of an object node. If this node is not an object (or it does not have a value for specified field name), or if there is no field with such name, null is returned.

Parameters

s:String

Name of the field (of Object node) to access

Returns:JrsValue

Node that represent value of the specified field, if this node is an Object and has value for the specified field; null otherwise.

@Override

Implements abstract com.fasterxml.jackson.jr.stree.JrsValue.get.

Implements com.fasterxml.jackson.core.TreeNode.get.

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

Method for accessing value of the specified element of an array node. For other nodes, null is returned.

For array nodes, index specifies exact location within array and allows for efficient iteration over child elements (underlying storage is guaranteed to be efficiently indexable, i.e. has random-access to elements). If index is less than 0, or equal-or-greater than node.size(), null is returned; no exception is thrown for any index.

Parameters

i:int

Index of the Array node element to access

Returns:JrsValue

Node that represent value of the specified element, if this node is an array and has specified element; null otherwise.

Annotations

@Override

Overrides java.lang.Object.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 com.fasterxml.jackson.core.TreeNode.isContainerNode.

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

Method that returns true for container nodes: Arrays and Objects.

Returns:boolean

True for Array and Object nodes, false otherwise

Annotations

@Override

Overrides com.fasterxml.jackson.jr.stree.JrsValue.isMissingNode.

Implements com.fasterxml.jackson.core.TreeNode.isMissingNode.

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

Method that returns true for "virtual" nodes which represent missing entries constructed by path accessor methods when there is no actual node matching given criteria.

Returns:boolean

True if this node represents a "missing" node

Annotations

@Override

Implements com.fasterxml.jackson.core.TreeNode.isValueNode.

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

Method that returns true for all value nodes: ones that are not containers, and that do not represent "missing" nodes in the path. Such value nodes represent String, Number, Boolean and null values from JSON.

Returns:boolean

True if this node is considered a value node; something that represents either a scalar value or explicit null

@Override

Implements abstract com.fasterxml.jackson.jr.stree.JrsValue.path.

Implements com.fasterxml.jackson.core.TreeNode.path.

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

Method for accessing value of the specified field of an object node. For other nodes, a "missing node" (virtual node for which isMissingNode returns true) is returned.

Parameters

s:String

Name of the field (of Object node) to access

Returns:JrsValue

Node that represent value of the specified field, if this node is an object and has value for the specified field; otherwise "missing node" is returned.

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

Method for accessing value of the specified element of an array node. For other nodes, a "missing node" (virtual node for which isMissingNode returns true) is returned.

For array nodes, index specifies exact location within array and allows for efficient iteration over child elements (underlying storage is guaranteed to be efficiently indexable, i.e. has random-access to elements). If index is less than 0, or equal-or-greater than node.size(), "missing node" is returned; no exception is thrown for any index.

Parameters

i:int

Index of the Array node element to access

Returns:JrsValue

@Override

Implements com.fasterxml.jackson.core.TreeNode.size.

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

Method that returns number of child nodes this node contains: for Array nodes, number of child elements, for Object nodes, number of fields, and for all other nodes 0.

Returns:int

For non-container nodes returns 0; for arrays number of contained elements, and for objects number of fields.

Annotations

@Override

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Returns:String

a string representation of the object
