StringEquals (lisa-sdk 0.1b6 API)

java.lang.Object
- it.unive.lisa.symbolic.value.operator.binary.StringOperation
- - it.unive.lisa.symbolic.value.operator.binary.StringEquals

All Implemented Interfaces:

Operator, BinaryOperator, StringOperator
```
public class StringEquals
extends StringOperation
```
Given two expressions that both evaluate to string values, a BinaryExpression using this operator checks if the string from the first argument is equal (in terms of contents, that is different from ComparisonEq) to the one of the second argument.

First argument expression type: StringType
Second argument expression type: StringType
Computed expression type: BooleanType
