ClassBuilder.FieldBuilder.FieldInitializerBuilder ​

com.jsmacrosce.jsmacros.core.library.impl.classes.ClassBuilder.FieldBuilder.FieldInitializerBuilder

Configures the value assigned to a field when it is added. Each operation replaces the previous initializer; this builder is returned by FieldBuilder.initializer().

Nested type declared in ClassBuilder.FieldBuilder.

Constructors ​

new ClassBuilder.FieldBuilder.FieldInitializerBuilder ​

new ClassBuilder.FieldBuilder.FieldInitializerBuilder(ClassBuilder.FieldBuilder fieldBuilder)#

Methods ​

callStaticMethod ​

callStaticMethod(Class<?> clazz, String methodName, String... code_arg): ClassBuilder.FieldBuilder#
Sets the field initializer to a call to a static method on another class. Arguments are Java source expressions, not values. 
builder.addField(Reflection.getClass("int"), "parsed")
  .initializer().callStaticMethod(
    Reflection.getClass("java.lang.Integer"), "parseInt", ""7"")
  .end();

Parameters:

  • clazz: the class declaring the static method
  • methodName: the name of the static method
  • code_arg: java source for the method's arguments
Returns: the field builder, so the field can be ended

callStaticMethodInThisClass ​

callStaticMethodInThisClass(String methodName, String... code_arg): ClassBuilder.FieldBuilder#
Sets the field initializer to a call to a static method on the generated class. Arguments are Java source expressions, not values. 
// a static method on the generated class, then a field that reads it
const factory = builder.addMethod(Reflection.getClass("int"), "defaultLimit");
factory.makePublic();
factory.toggleStatic();
factory.body("{ return 10; }");

builder.addField(Reflection.getClass("int"), "limit")
  .initializer().callStaticMethodInThisClass("defaultLimit")
  .end();

Parameters:

  • methodName: the name of the static method on this class
  • code_arg: java source for the method's arguments
Returns: the field builder, so the field can be ended

compile ​

compile(String code): ClassBuilder.FieldBuilder#
Sets the initializer to a Java source expression, evaluated once when the field is initialized. The expression is not in a constructor body and has no instance available, so it cannot reference instance members. 
builder.addField(Reflection.getClass("int"), "answer")
  .initializer().compile("6 * 7")
  .end();

Parameters:

  • code: the java source of the expression to evaluate
Returns: the field builder, so the field can be ended

initClass ​

initClass(Class<?> clazz, String... code_arg): ClassBuilder.FieldBuilder#
Sets the initializer to a constructor call. Each argument is Java source for a constructor parameter; the argument forms determine which overloaded constructor is selected.

Parameters:

  • clazz: the class to make an instance of
  • code_arg: Java source expressions for the constructor arguments
Returns: the field builder, so the field can be ended

setBoolean ​

setBoolean(boolean value): ClassBuilder.FieldBuilder#
Sets the field initializer to a boolean constant.

Parameters:

  • value: the value to start the field at
Returns: the field builder, so the field can be ended

setByte ​

setByte(byte value): ClassBuilder.FieldBuilder#
Sets the field initializer to a byte constant.

Parameters:

  • value: the value to start the field at
Returns: the field builder, so the field can be ended

setChar ​

setChar(char value): ClassBuilder.FieldBuilder#
Sets the field initializer to a char constant.

Parameters:

  • value: the character to start the field at
Returns: the field builder, so the field can be ended

setDouble ​

setDouble(double value): ClassBuilder.FieldBuilder#
Sets the field initializer to a double constant.

Parameters:

  • value: the value to start the field at
Returns: the field builder, so the field can be ended

setFloat ​

setFloat(double value): ClassBuilder.FieldBuilder#
Sets the field initializer to a float constant, narrowing the input double to float.

Parameters:

  • value: the value to convert to float
Returns: the field builder, so the field can be ended

setInt ​

setInt(int value): ClassBuilder.FieldBuilder#
Sets the field initializer to an integer constant.

Parameters:

  • value: the value to start the field at
Returns: the field builder, so the field can be ended

setLong ​

setLong(long value): ClassBuilder.FieldBuilder#
Sets the field initializer to a long constant.

Parameters:

  • value: the value to start the field at
Returns: the field builder, so the field can be ended

setShort ​

setShort(short value): ClassBuilder.FieldBuilder#
Sets the field initializer to a short constant.

Parameters:

  • value: the value to start the field at
Returns: the field builder, so the field can be ended

setString ​

setString(String value): ClassBuilder.FieldBuilder#
Sets the field initializer to a string constant.

Parameters:

  • value: the value to start the field at
Returns: the field builder, so the field can be ended
