Methods

Modifier and Type	Method and Description
protected void	appendNode(java.lang.Object newValue) NOP, because an node can not be appended to an attribute.
void	build(GroovyObject builder)

Constructor Detail

Attribute

public Attribute(java.lang.String name,
         java.lang.String value,
         GPathResult parent,
         java.lang.String namespacePrefix,
         java.util.Map<java.lang.String,java.lang.String> namespaceTagHints)

Parameters:

name - of the attribute

value - of the attribute

parent - the GPathResult prior to the application of the expression creating this GPathResult

namespacePrefix - the namespace prefix if any

namespaceTagHints - the known tag to namespace mappings

Method Detail

name

public java.lang.String name()

Description copied from class: GPathResult

Returns the name of this GPathResult.

Overrides:

name in class GPathResult

Returns:

the name of this GPathResult

size

public int size()

Returns the size of this Attribute, which is always 1.

Specified by:

size in class GPathResult

Returns:

1

text

public java.lang.String text()

Returns the value of this Attribute.

Specified by:

text in class GPathResult

Returns:

the value of this Attribute

namespaceURI

public java.lang.String namespaceURI()

Returns the URI of the namespace of this Attribute.

Returns:

the namespace of this Attribute

parents

public GPathResult parents()

Throws a GroovyRuntimeException, because this method is not implemented yet.

Specified by:

parents in class GPathResult

Returns:

the parents of this GPathResult

childNodes

public java.util.Iterator childNodes()

Throws a GroovyRuntimeException, because an attribute can have no children.

Specified by:

childNodes in class GPathResult

Returns:

an iterator over the child nodes of this GPathResult

iterator

public java.util.Iterator iterator()

Specified by:

iterator in class GPathResult

find

public GPathResult find(Closure closure)

Description copied from class: GPathResult

Returns the first child of this GPathResult matching the condition(s) specified in the passed closure.

Specified by:

find in class GPathResult

Parameters:

closure - a closure to filters the children of this GPathResult

Returns:

the first child matching the closure

findAll

public GPathResult findAll(Closure closure)

Description copied from class: GPathResult

Returns the children of this GPathResult matching the condition(s) specified in the passed closure.

Specified by:

findAll in class GPathResult

Parameters:

closure - a closure to filters the children of this GPathResult

Returns:

the children matching the closure

nodeIterator

public java.util.Iterator nodeIterator()

Specified by:

nodeIterator in class GPathResult

writeTo

public java.io.Writer writeTo(java.io.Writer out)
                       throws java.io.IOException

Description copied from interface: Writable

Writes this object to the given writer.

This is used to defer content creation until the point when it is streamed to the output destination. Oftentimes, content will be defined but not necessarily created (as is may be the case with a Closure definition.) In that case, the output is then 'deferred' to the point when it is serialized to the writer. This class may be used whenever an object should be responsible for creating its own textual representation, but creating the entire output as a single String would be inefficient (such as outputting a multi-gigabyte XML document.)

Parameters:

out - the Writer to which this Writable should output its data.

Returns:

the Writer that was passed

Throws:

java.io.IOException - if an error occurred while outputting data to the writer

build

public void build(GroovyObject builder)

replaceNode

protected void replaceNode(Closure newValue)

NOP, because an attribute does not have any Node to replace.

Specified by:

replaceNode in class GPathResult

replaceBody

protected void replaceBody(java.lang.Object newValue)

NOP, because an attribute does not have a Body.

Specified by:

replaceBody in class GPathResult

appendNode

protected void appendNode(java.lang.Object newValue)

NOP, because an node can not be appended to an attribute.

Specified by:

appendNode in class GPathResult
