Constructor Detail

SubstRuleFormat3

public SubstRuleFormat3(List<Set<Integer>> coverages,
                        SubstLookupRecord[] substLookupRecords)

Method Detail

getContextLength

public int getContextLength()

Specified by:

getContextLength in class ContextualSubstRule

Returns:

length of the context glyph sequence defined by this rule.

getSubstLookupRecords

public SubstLookupRecord[] getSubstLookupRecords()

Specified by:

getSubstLookupRecords in class ContextualSubstRule

Returns:

an array of SubstLookupRecord. Each record specifies a position in the context glyph sequence and a LookupListIndex to the substitution lookup that is applied at that position.

isGlyphMatchesInput

public boolean isGlyphMatchesInput(int glyphId,
                                   int atIdx)

Description copied from class: ContextualSubstRule

Checks if glyph line element matches element from input sequence of the rule.

NOTE: rules do not contain the first element of the input sequence, the first element is defined by rule position in substitution table. Therefore atIdx shall not be 0.

Specified by:

isGlyphMatchesInput in class ContextualSubstRule

atIdx - index in the rule sequence. Shall be: 0 < atIdx < ContextualSubstRule.getContextLength().
