Constructor Details

ConstantExpression

public ConstantExpression(Object value,
 Type type)

Creates an instance of a ConstantExpression record class.

Parameters:

value - the value for the value record component

type - the value for the type record component

Method Details

fromJson

public static ConstantExpression fromJson(Block value,
 Type type)

getBlockValue

public Block getBlockValue()

toString

public String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in interface RowExpression

Specified by:

toString in class Record

Returns:

a string representation of this object

accept

public <R,
C> R accept(RowExpressionVisitor<R,C> visitor,
 C context)

Specified by:

accept in interface RowExpression

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in interface RowExpression

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in interface RowExpression

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

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

value

public Object value()

Returns the value of the value record component.

Returns:

the value of the value record component

type

public Type type()

Returns the value of the type record component.

Specified by:

type in interface RowExpression

Returns:

the value of the type record component
