Woodstox 6.5.1 · com.ctc.wstx.sr.ElemAttrs · APIdia, the JavaDoc alternative

Container class that is constructed with enough raw attribute information, to be able to lazily construct full attribute objects, to be accessed via Iterator, or fully-qualified name.

Implementation Note

code for using Map-like structure is unfortunately cut'n pasted from AttributeCollector. Problem with refactoring is that it's 90% the same code, but not 100%.

Although instances of this class are constructed by stream readers, it is actually used by element event objects.

Constructor Detail

ElemAttrs	back to summary
public ElemAttrs(String[] rawAttrs, int defOffset) Method called to create "short" attribute list; list that has only few entries, and can thus be searched for attributes using linear search, without using any kind of Map structure. Currently the limit is 4 attributes; 1, 2 or 3 attribute lists are considered short, 4 or more 'long'. Parameters rawAttrs:String[] Array that contains 4 Strings for each attribute; localName, URI, prefix, value. Can be used to lazily construct structure(s) needed to return Iterator for accessing all attributes. defOffset:int Index of the first default attribute, if any; number of all attributes if none

ElemAttrs

back to summary

public ElemAttrs(String[] rawAttrs, int defOffset)

Method called to create "short" attribute list; list that has only few entries, and can thus be searched for attributes using linear search, without using any kind of Map structure.

Currently the limit is 4 attributes; 1, 2 or 3 attribute lists are considered short, 4 or more 'long'.

Parameters

rawAttrs:String[]: Array that contains 4 Strings for each attribute; localName, URI, prefix, value. Can be used to lazily construct structure(s) needed to return Iterator for accessing all attributes.
defOffset:int: Index of the first default attribute, if any; number of all attributes if none

ElemAttrs	back to summary
public ElemAttrs(String[] rawAttrs, int defOffset, int[] attrMap, int hashSize, int spillEnd) Method called to create "long" attribute list; list that has a few entries, and efficient access by fully-qualified name should not be done by linear search. Parameters rawAttrs:String[] Array that contains 4 Strings for each attribute; localName, URI, prefix, value. Can be used to lazily construct structure(s) needed to return Iterator for accessing all attributes.

ElemAttrs

back to summary

public ElemAttrs(String[] rawAttrs, int defOffset, int[] attrMap, int hashSize, int spillEnd)

Method called to create "long" attribute list; list that has a few entries, and efficient access by fully-qualified name should not be done by linear search.

Parameters

rawAttrs:String[]: Array that contains 4 Strings for each attribute; localName, URI, prefix, value. Can be used to lazily construct structure(s) needed to return Iterator for accessing all attributes.

public int findIndex(QName name)

findMapIndex	back to summary
private final int findMapIndex(String nsURI, String localName) Note this method is very similar to `com.ctc.wstx.sr.AttributeCollector#getAttrValue`; basically most of it was cut'n pasted. Would be nice to refactor, but it's bit hard to do that since data structures are not 100% identical (mostly attribute storage, not Map structure itself).
