Method Detail

getGrammarType

public String getGrammarType()

Description copied from interface: XMLGrammarDescription

Return the type of this grammar.

Specified by:

getGrammarType in interface XMLGrammarDescription

Returns:

the type of this grammar

getRootName

public String getRootName()

Description copied from interface: XMLDTDDescription

Return the root name of this DTD.

Specified by:

getRootName in interface XMLDTDDescription

Returns:

the root name of this DTD or null if root name is unknown

setRootName

public void setRootName(String rootName)

Set the root name

setPossibleRoots

public void setPossibleRoots(ArrayList possibleRoots)

Set possible roots

setPossibleRoots

public void setPossibleRoots(Vector possibleRoots)

Set possible roots

equals

public boolean equals(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 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
