WhitespaceTextImpl
Create a compressed whitespace text node- Parameters:
tree
- the tree to contain the nodenodeNr
- the internal node number
-
-
Method Details
-
getStringValue
Return the character value of the node.- Returns:
- the string value of the node
- See Also:
-
getStringValueCS
Get the value of the item as a CharSequence. This is in some cases more efficient than the version of the method that returns a String. For a WhitespaceTextImpl node, it avoids the cost of decompressing the whitespace- Specified by:
getStringValueCS
in interfaceItem<NodeInfo>
- Specified by:
getStringValueCS
in interfaceValueRepresentation<NodeInfo>
- Overrides:
getStringValueCS
in classTinyNodeImpl
- Returns:
- the string value of the item
- See Also:
-
getStringValueCS
Static method to get the string value of a text node without first constructing the node object- Parameters:
tree
- the treenodeNr
- the node number of the text node- Returns:
- the string value of the text node
-
appendStringValue
Static method to get the string value of a text node and append it to a supplied buffer without first constructing the node object- Parameters:
tree
- the treenodeNr
- the node number of the text nodebuffer
- a buffer to which the string value will be appended
-
atomize
Get the typed value. The result of this method will always be consistent with the methodItem.getTypedValue()
. However, this method is often more convenient and may be more efficient, especially in the common case where the value is expected to be a singleton.- Returns:
- the typed value. This will either be a single AtomicValue or a Value whose items are atomic values.
- Throws:
XPathException
- if the node has no typed value, for example if it is an element node with element-only content- Since:
- 8.5
-
getTypedValue
Get the typed value of the item. For a node, this is the typed value as defined in the XPath 2.0 data model. Since a node may have a list-valued data type, the typed value is in general a sequence, and it is returned in the form of a SequenceIterator. If the node has not been validated against a schema, the typed value will be the same as the string value, either as an instance of xs:string or as an instance of xs:untypedAtomic, depending on the node kind. For an atomic value, this method returns an iterator over a singleton sequence containing the atomic value itself.- Returns:
- an iterator over the items in the typed value of the node or atomic value. The items returned by this iterator will always be atomic values.
- Throws:
XPathException
- where no typed value is available, for example in the case of an element with complex content- Since:
- 8.4
-
getLongValue
Static method to get the "long" value representing the content of a whitespace text node- Parameters:
tree
- the TinyTreenodeNr
- the internal node number- Returns:
- a value representing the compressed whitespace content
- See Also:
-
getNodeKind
public final int getNodeKind()Return the type of node.- Returns:
- Type.TEXT
- See Also:
-
copy
Copy this node to a given outputter- Parameters:
out
- the Receiver to which the node should be copied. It is the caller's responsibility to ensure that this Receiver is open before the method is called (or that it is self-opening), and that it is closed after use.copyOptions
- a selection of the options defined inCopyOptions
locationId
- If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information- Throws:
XPathException
- if any downstream error occurs
-
