  • Method Details

    • startDelimiterToken

      public SaaStTemplateRenderer.Builder startDelimiterToken(char startDelimiterToken)
      Sets the character used as the start delimiter for template expressions. Default is '{'.
      Parameters:
      startDelimiterToken - The start delimiter character.
      Returns:
      This builder instance for chaining.

    • endDelimiterToken

      public SaaStTemplateRenderer.Builder endDelimiterToken(char endDelimiterToken)
      Sets the character used as the end delimiter for template expressions. Default is '}'.
      Parameters:
      endDelimiterToken - The end delimiter character.
      Returns:
      This builder instance for chaining.

    • startDelimiter

      public SaaStTemplateRenderer.Builder startDelimiter(String startDelimiterString)
      Sets the string used as the start delimiter for template expressions. This allows using multi-character delimiters (e.g., "{{") which is useful for avoiding conflicts with JSON content or other text that uses single-character delimiters.

      When string delimiters are set, they take precedence over character delimiters.

      Parameters:
      startDelimiterString - The start delimiter string (e.g., "{{").
      Returns:
      This builder instance for chaining.

    • endDelimiter

      public SaaStTemplateRenderer.Builder endDelimiter(String endDelimiterString)
      Sets the string used as the end delimiter for template expressions. This allows using multi-character delimiters (e.g., "}}") which is useful for avoiding conflicts with JSON content or other text that uses single-character delimiters.

      When string delimiters are set, they take precedence over character delimiters.

      Parameters:
      endDelimiterString - The end delimiter string (e.g., "}}").
      Returns:
      This builder instance for chaining.

    • validationMode

      public SaaStTemplateRenderer.Builder validationMode(org.springframework.ai.template.ValidationMode validationMode)
      Sets the validation mode to control behavior when the provided variables do not match the variables required by the template. Default is ValidationMode.THROW.
      Parameters:
      validationMode - The desired validation mode.
      Returns:
      This builder instance for chaining.

    • validateStFunctions

      public SaaStTemplateRenderer.Builder validateStFunctions()
      Configures the renderer to support StringTemplate's built-in functions during validation.

      When enabled (set to true), identifiers in the template that match known ST function names (e.g., "first", "rest", "length") will not be treated as required input variables during validation.

      When disabled (default, false), these identifiers are treated like regular variables and must be provided in the input map if validation is enabled (ValidationMode.WARN or ValidationMode.THROW).

      Returns:
      This builder instance for chaining.

    • build

      public SaaStTemplateRenderer build()
      Builds and returns a new SaaStTemplateRenderer instance with the configured settings.
      Returns:
      A configured SaaStTemplateRenderer.
