com.itextpdf.io.font.otf Documentation Differences

This file contains all the changes in documentation in the package com.itextpdf.io.font.otf as colored differences. Deletions are shown like this , and additions are shown like this.
If no deletions or additions are shown in an entry, the HTML tags will be what has changed. The new HTML tags are shown in the differences. If no documentation existed, and then some was added in a later version, this change is noted in the appropriate class pages of differences, but the change is not shown on this page. Only changes in existing text are shown here. Similarly, documentation which was inherited from another class or interface is not shown here.
Note that an HTML error in the new documentation may cause the display of other documentation changes to be presented incorrectly. For instance, failure to close a tag will cause all subsequent paragraphs to be displayed differently.

Class ContextualSubstRule, int getBacktrackContextLength()

@return Gets the length of the backtrack context glyph sequence defined by this rule. rule @return length of the backtrack context
Class ContextualSubstRule, int getContextLength()

@return Gets the length of the context glyph sequence defined by this rule. rule @return length of the context
Class ContextualSubstRule, int getLookaheadContextLength()

@return Gets the length of the lookahead context glyph sequence defined by this rule. rule @return length of the lookahead context
Class ContextualSubstRule, SubstLookupRecord[] getSubstLookupRecords()

@return Retrieves an array of the substitution lookup SubstLookupRecord records. Each record specifies a position in the context glyph sequence and a LookupListIndex to the substitution lookup that is applied at that position. @return an array of SubstLookupRecord.
Class ContextualSubstRule, boolean isGlyphMatchesBacktrack(int, int)

Checks if glyph line element matches element from backtrack sequence of the rule. @param glyphId glyphId glyph code id @param atIdx index in rule sequence. Shall be: 0 <= atIdx < ContextualSubstRule.getBacktrackContextLength() . @return {@code true} if glyph matches element from backtrack sequence
Class ContextualSubstRule, boolean isGlyphMatchesInput(int, int)

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. @param glyphId glyphId glyph code id @param atIdx index in the rule sequence. Shall be: 0 < atIdx < ContextualSubstRule.getContextLength (). @return {@code true} if glyph matches element
Class ContextualSubstRule, boolean isGlyphMatchesLookahead(int, int)

Checks if glyph line element matches element from lookahead sequence of the rule. @param glyphId glyphId glyph code id @param atIdx index in rule sequence. Shall be: 0 <= atIdx < ContextualSubstRule.getLookaheadContextLength() . @return {@code true} if glyph matches element from lookahead sequence
