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

that:Object

the reference object with which to compare.

Returns:boolean

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

@Override

Implements org.w3c.dom.css.CSSStyleDeclaration.getCssText.

Doc from org.w3c.dom.css.CSSStyleDeclaration.getCssText.

The parsable textual representation of the declaration block (excluding the surrounding curly braces). Setting this attribute will result in the parsing of the new value and resetting of all the properties in the declaration block including the removal or addition of properties.

Implements org.w3c.dom.css.CSSStyleDeclaration.getLength.

Doc from org.w3c.dom.css.CSSStyleDeclaration.getLength.

The number of properties that have been explicitly set in this declaration block. The range of valid indices is 0 to length-1 inclusive.

Implements org.w3c.dom.css.CSSStyleDeclaration.getParentRule.

Doc from org.w3c.dom.css.CSSStyleDeclaration.getParentRule.

The CSS rule that contains this declaration block or null if this CSSStyleDeclaration is not attached to a CSSRule.

Implements org.w3c.dom.css.CSSStyleDeclaration.getPropertyCSSValue.

Doc from org.w3c.dom.css.CSSStyleDeclaration.getPropertyCSSValue.

Used to retrieve the object representation of the value of a CSS property if it has been explicitly set within this declaration block. This method returns null if the property is a shorthand property. Shorthand property values can only be accessed and modified as strings, using the getPropertyValue and setProperty methods.

Parameters

propertyName:String

The name of the CSS property. See the CSS property index.

Returns:CSSValue

Returns the value of the property if it has been explicitly set for this declaration block. Returns null if the property has not been set.

Implements org.w3c.dom.css.CSSStyleDeclaration.getPropertyPriority.

Doc from org.w3c.dom.css.CSSStyleDeclaration.getPropertyPriority.

Used to retrieve the priority of a CSS property (e.g. the "important" qualifier) if the priority has been explicitly set in this declaration block.

Parameters

propertyName:String

The name of the CSS property. See the CSS property index.

Returns:String

A string representing the priority (e.g. "important") if the property has been explicitly set in this declaration block and has a priority specified. The empty string otherwise.

Implements org.w3c.dom.css.CSSStyleDeclaration.getPropertyValue.

Doc from org.w3c.dom.css.CSSStyleDeclaration.getPropertyValue.

Used to retrieve the value of a CSS property if it has been explicitly set within this declaration block.

Parameters

propertyName:String

The name of the CSS property. See the CSS property index.

Returns:String

Returns the value of the property if it has been explicitly set for this declaration block. Returns the empty string if the property has not been set.

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

Annotations

@Override

Implements org.w3c.dom.css.CSSStyleDeclaration.item.

Doc from org.w3c.dom.css.CSSStyleDeclaration.item.

Used to retrieve the properties that have been explicitly set in this declaration block. The order of the properties retrieved using this method does not have to be the order in which they were set. This method can be used to iterate over all properties in this declaration block.

Parameters

index:int

Index of the property name to retrieve.

Returns:String

The name of the property at this ordinal position. The empty string if no property exists at this position.

Implements org.w3c.dom.css.CSSStyleDeclaration.removeProperty.

Doc from org.w3c.dom.css.CSSStyleDeclaration.removeProperty.

Used to remove a CSS property if it has been explicitly set within this declaration block.

Parameters

propertyName:String

The name of the CSS property. See the CSS property index.

Returns:String

Returns the value of the property if it has been explicitly set for this declaration block. Returns the empty string if the property has not been set or the property name does not correspond to a known CSS property.

Exceptions

DOMException:

NO_MODIFICATION_ALLOWED_ERR: Raised if this declaration is readonly or the property is readonly.

Implements org.w3c.dom.css.CSSStyleDeclaration.setCssText.

Doc from org.w3c.dom.css.CSSStyleDeclaration.setCssText.

The parsable textual representation of the declaration block (excluding the surrounding curly braces). Setting this attribute will result in the parsing of the new value and resetting of all the properties in the declaration block including the removal or addition of properties.

Exceptions

DOMException:

SYNTAX_ERR: Raised if the specified CSS string value has a syntax error and is unparsable.
NO_MODIFICATION_ALLOWED_ERR: Raised if this declaration is readonly or a property is readonly.

Implements org.w3c.dom.css.CSSStyleDeclaration.setProperty.

Doc from org.w3c.dom.css.CSSStyleDeclaration.setProperty.

Used to set a property value and priority within this declaration block. setProperty permits to modify a property or add a new one in the declaration block. Any call to this method may modify the order of properties in the item method.

Parameters

propertyName:String

The name of the CSS property. See the CSS property index.

value:String

The new value of the property.

priority:String

The new priority of the property (e.g. "important") or the empty string if none.

Exceptions

DOMException:

SYNTAX_ERR: Raised if the specified value has a syntax error and is unparsable.
NO_MODIFICATION_ALLOWED_ERR: Raised if this declaration is readonly or the property is readonly.
