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

NodeChild

public NodeChild(Node node,
         GPathResult parent,
         java.util.Map<java.lang.String,java.lang.String> namespaceTagHints)

Parameters:

node - a node

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

namespaceTagHints - the known tag to namespace mappings

Method Detail

size

public int size()

Description copied from class: GPathResult

Returns the size of this GPathResult.

Specified by:

size in class GPathResult

Returns:

the size of this GPathResult

text

public java.lang.String text()

Description copied from class: GPathResult

Returns the text of this GPathResult as a String.

Specified by:

text in class GPathResult

Returns:

the text of this GPathResult

namespaceURI

public java.lang.String namespaceURI()

Returns the URI of the namespace of this NodeChild.

Returns:

the namespace of this NodeChild

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

iterator

public java.util.Iterator iterator()

Specified by:

iterator in class GPathResult

nodeIterator

public java.util.Iterator nodeIterator()

Specified by:

nodeIterator in class GPathResult

getAt

public java.lang.Object getAt(int index)

Description copied from class: GPathResult

Supports the subscript operator for a GPathResult.

 def text = """
 <characterList>
   <character/>
   <character>
     <name>Gromit</name>
   </character>
 </characterList>"""

 GPathResult characterList = new XmlSlurper().parseText(text)

 assert characterList.character[1].name == 'Gromit'
 

Overrides:

getAt in class GPathResult

Parameters:

index - an index

Returns:

the value at the given index

attributes

public java.util.Map attributes()

Returns a map containing all attributes of the Node of this NodeChild.

Returns:

a map containing all attributes

childNodes

public java.util.Iterator childNodes()

Description copied from class: GPathResult

Returns an iterator over the child nodes of this GPathResult.

Specified by:

childNodes in class GPathResult

Returns:

an iterator over the child nodes of this 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:

build

public void build(GroovyObject builder)

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

replaceNode in class GPathResult

replaceBody

protected void replaceBody(java.lang.Object newValue)

Specified by:

replaceBody in class GPathResult

appendNode

protected void appendNode(java.lang.Object newValue)

Specified by:

appendNode in class GPathResult
