Method Details

getFunctionId

public FunctionId getFunctionId()

Unique id of this function. For aliased functions, each alias must have a different alias.

getSignature

public Signature getSignature()

Signature of a matching call site. For aliased functions, the signature must use the alias name.

getCanonicalName

public String getCanonicalName()

For aliased functions, the canonical name of the function.

getFunctionNullability

public FunctionNullability getFunctionNullability()

isHidden

public boolean isHidden()

isDeterministic

public boolean isDeterministic()

getDescription

public String getDescription()

getKind

public FunctionKind getKind()

isDeprecated

public boolean isDeprecated()

toString

public String toString()

Overrides:
