Constructors

constructor

new ExpressionBuilder(): ExpressionBuilder
Returns ExpressionBuilder

Methods

createArrayLiteral

createArrayLiteral(elements: Expression[]): ArrayLiteralExpression
Creates an array literal expression.
Parameters
- elements: Expression[]
  Array of AST Expressions.
Returns ArrayLiteralExpression
Example
```
[elem1, elem2]
```
- Defined in core/generator/writers/core/expression-builder.ts:41

createArrowFunctionReturningIdentifier

createArrowFunctionReturningIdentifier(identifierName: string): ArrowFunction
Creates an arrow function that returns an identifier.
Parameters
- identifierName: string
Returns ArrowFunction
Example
```
() => GuardDogTraits
```
- Defined in core/generator/writers/core/expression-builder.ts:12

createBooleanLiteral

createBooleanLiteral(value: boolean): BooleanLiteral
Creates a boolean literal (true or false)
Parameters
- value: boolean
Returns BooleanLiteral
- Defined in core/generator/writers/core/expression-builder.ts:46

createIdentifier

createIdentifier(name: string): Identifier
Creates an identifier (e.g., a class name reference like GuardDogTraits)
Parameters
- name: string
Returns Identifier
- Defined in core/generator/writers/core/expression-builder.ts:72

createNumericLiteral

createNumericLiteral(value: number): Expression
Creates a numeric literal, wrapping negative values in a unary minus. ts.factory.createNumericLiteral asserts on negative input, so the sign has to be modelled as a prefix expression rather than baked into the literal.
Parameters
- value: number
Returns Expression
- Defined in core/generator/writers/core/expression-builder.ts:55

createObjectLiteral

createObjectLiteral(
props: Record<string, ts.Expression>,
): ObjectLiteralExpression
Creates an object literal expression.
Parameters
- props: Record<string, ts.Expression>
  A map of key-value pairs where values are AST Expressions.
Returns ObjectLiteralExpression
Example
```
{ keepDiscriminatorProperty: true }
```
- Defined in core/generator/writers/core/expression-builder.ts:28

createStringLiteral

createStringLiteral(text: string): StringLiteral
Creates a string literal ("text")
Parameters
- text: string
Returns StringLiteral
- Defined in core/generator/writers/core/expression-builder.ts:67
