Methods

CompareBooleanExpressions(BooleanExpression, BooleanExpression)

Compares two boolean expressions and returns true unless left is true and right is false.

Declaration
protected override bool CompareBooleanExpressions(BooleanExpression left, BooleanExpression right)
Parameters
BooleanExpression left

The left.
BooleanExpression right

The right.
Returns
System.Boolean

Boolean result.
Overrides

CompareDifferentTypeExpressions(ConstantExpression, ConstantExpression)

Compares expressions of different types and returns true if the left type has lower precedence than the right type.

Declaration
protected override bool CompareDifferentTypeExpressions(ConstantExpression leftOperandValue, ConstantExpression rightOperandValue)
Parameters
ConstantExpression leftOperandValue

The left operand value.
ConstantExpression rightOperandValue

The right operand value.
Returns
System.Boolean

Boolean result.
Overrides

CompareEmptyExpressions(EmptyExpression, EmptyExpression)

Compares two empty expressions and always returns true since empty values are equal.

Declaration
protected override bool CompareEmptyExpressions(EmptyExpression left, EmptyExpression right)
Parameters
EmptyExpression left

The left.
EmptyExpression right

The right.
Returns
System.Boolean

Boolean result.
Overrides

CompareNumberExpressions(NumberExpression, NumberExpression)

Declaration
protected override bool CompareNumberExpressions(NumberExpression left, NumberExpression right)
Parameters
NumberExpression left

The left.
NumberExpression right

The right.
Returns
System.Boolean

Boolean result.
Overrides

CompareStringExpressions(StringExpression, StringExpression)

Compares two string expressions and returns true if the left is alphabetically less than or equal to the right using case-insensitive comparison.
