方法详细资料

getGatedPredicateContext

public SemanticContext getGatedPredicateContext()

从类复制的说明: SemanticContext

Given a semantic context expression tree, return a tree with all nongated predicates set to true and then reduced. So p&&(q||r) would return p&&r if q is nongated but p and r are gated.

指定者:

getGatedPredicateContext 在类中 SemanticContext

hasUserSemanticPredicate

public boolean hasUserSemanticPredicate()

指定者:

hasUserSemanticPredicate 在类中 SemanticContext

isSyntacticPredicate

public boolean isSyntacticPredicate()

指定者:

isSyntacticPredicate 在类中 SemanticContext

trackUseOfSyntacticPredicates

public void trackUseOfSyntacticPredicates(Grammar g)

从类复制的说明: SemanticContext

Notify the indicated grammar of any syn preds used within this context

覆盖:

trackUseOfSyntacticPredicates 在类中 SemanticContext

equals

public boolean equals(java.lang.Object obj)

覆盖:

equals 在类中 java.lang.Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 java.lang.Object

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object

getOperandString

public abstract java.lang.String getOperandString()

combinePredicates

public abstract SemanticContext combinePredicates(SemanticContext left,
                                                  SemanticContext right)

calculateHashCode

public abstract int calculateHashCode()
