Field Detail

parentsback to summary
public final PredictionContext[] parents

Parent can be null only if full ctx mode and we make an array from EMPTY and non-empty. We merge EMPTY by using null parent and returnState == EMPTY_RETURN_STATE.

returnStatesback to summary
public final int[] returnStates

Sorted for merge, no duplicates; if present, EMPTY_RETURN_STATE is always last.

equalsback to summary
public boolean equals(Object o)

Implements abstract org.antlr.v4.runtime.atn.PredictionContext.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.
