Constructor Detail

PosRuleFormat2

public PosRuleFormat2(PosTableLookup7Format2 subTable,
                      int[] inputClassIds,
                      PosLookupRecord[] posLookupRecords)

Method Detail

getContextLength

public int getContextLength()

Description copied from class: ContextualRule

Gets the length of the context glyph sequence defined by this rule

Specified by:

getContextLength in class ContextualRule

Returns:

length of the context

getPosLookupRecords

public PosLookupRecord[] getPosLookupRecords()

Description copied from class: ContextualPositionRule

Retrieves the position lookup records. Each record specifies a position in the context glyph sequence and a LookupListIndex to the position lookup that is applied at that position.

Specified by:

getPosLookupRecords in class ContextualPositionRule

Returns:

an array of PosLookupRecord.

isGlyphMatchesInput

public boolean isGlyphMatchesInput(int glyphId,
                                   int atIdx)

Description copied from class: ContextualRule

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 ContextualRule

Parameters:

glyphId - glyph code id

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

Returns:

true if glyph matches element
