List of LA() Examples

Examples of LA()

org.antlr.runtime.IntStream.LA()
Get int at current input pointer + i ahead where i=1 is next int. Negative indexes are allowed. LA(-1) is previous token (token just matched). LA(-i) where i is before first token should yield -1, invalid char / EOF.
org.antlr.runtime.tree.CommonTreeNodeStream.LA()
org.antlr.v4.runtime.CharStream.LA()
org.antlr.v4.runtime.CommonTokenStream.LA()
org.antlr.v4.runtime.TokenStream.LA()

Examples of org.antlr.v4.runtime.CharStream.LA()
