Method Detail

getGrammarType

public java.lang.String getGrammarType()
Description copied from interface: org.apache.xerces.xni.grammars.XMLGrammarDescription
Return the type of this grammar.

Specified by:
getGrammarType in interface org.apache.xerces.xni.grammars.XMLGrammarDescription
Returns:
the type of this grammar

getRootName

public java.lang.String getRootName()
Description copied from interface: org.apache.xerces.xni.grammars.XMLDTDDescription
Return the root name of this DTD.

Specified by:
getRootName in interface org.apache.xerces.xni.grammars.XMLDTDDescription
Returns:
the root name of this DTD or null if root name is unknown

setRootName

public void setRootName(java.lang.String rootName)
Set the root name


setPossibleRoots

public void setPossibleRoots(java.util.ArrayList possibleRoots)
Set possible roots


setPossibleRoots

public void setPossibleRoots(java.util.Vector possibleRoots)
Set possible roots


equals

public boolean equals(java.lang.Object desc)
Compares this grammar with the given grammar. Currently, we compare as follows: - if grammar type not equal return false immediately - try and find a common root name: - if both have roots, use them - else if one has a root, examine other's possible root's for a match; - else try all combinations - test fExpandedSystemId and fPublicId as above

Overrides:
equals in class java.lang.Object
Parameters:
desc - The description of the grammar to be compared with
Returns:
True if they are equal, else false

hashCode

public int hashCode()
Returns the hash code of this grammar Because our .equals method is so complex, we just return a very simple hash that might avoid calls to the equals method a bit...

Overrides:
hashCode in class XMLResourceIdentifierImpl
Returns:
The hash code
