Method Details

values

public static Operator[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Operator valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

getBinaryPrecedence

public int getBinaryPrecedence()

getPrettyName

public String getPrettyName()

Returns the operator name surrounded by the expected whitespace for a tidy binary expression.

toString

public String toString()

Returns the operator name without any surrounding whitespace.

Overrides:

toString in class Enum<Operator>

isEquality

public boolean isEquality()

isRelational

public boolean isRelational()

Defines the set of relational (comparison) operators: invalid input: '<' invalid input: '<'= > >=

isAssignment

public boolean isAssignment()

Returns true if op is '=' or any compound assignment operator ('+=', '-=', etc.)

removeAssignment

public Operator removeAssignment()

Given a compound assignment operator, returns the non-assignment version of the operator (e.g. '+=' becomes '+')

isOnlyValidForIntegers

public boolean isOnlyValidForIntegers()

Defines the set of operators which are only valid on integral types: % %= invalid input: '<'invalid input: '<' invalid input: '<'invalid input: '<'= >> >>= ~ invalid input: '&' invalid input: '&'= | |= ^ ^=

isValidForVectorOrMatrix

public boolean isValidForVectorOrMatrix()

Defines the set of operators which perform vector/matrix math. + += - -= * *= / /= % %= invalid input: '<'invalid input: '<' invalid input: '<'invalid input: '<'= >> >>= invalid input: '&' invalid input: '&'= | |= ^ ^=

determineBinaryType

public boolean determineBinaryType(Context context,
 Type left,
 Type right,
 Type[] out)

Determines the operand and result types of a binary expression. Returns true if the expression is legal, false otherwise. If false, the values of the out parameters are undefined.

Parameters:

out - left type, right type and result type, respectively
