Method Summary

Modifier and Type	Method and Description
String[]	build() Retrieves all arguments as a string array, usable by a method accepting a String[] for argument.
ArgumentBuilder	withFlag(boolean addFlag, String flag) Adds a flag on the form -someflag to the list of arguments contained within this ArgumentBuilder.
ArgumentBuilder	withNamedArgument(boolean addNamedArgument, String name, String value) Adds a name and an argument on the form -name value to the list of arguments contained within this ArgumentBuilder.
ArgumentBuilder	withNamedArgument(String name, String value) Convenience form for the withNamedArgument method, where a named argument is only added if the value is non-null and non-empty after trimming.
ArgumentBuilder	withPreCompiledArguments(List<String> preCompiledArguments) Adds the supplied pre-compiled arguments in the same order as they were given.

public ArgumentBuilder()

Method Detail

build

public String[] build()

Retrieves all arguments as a string array, usable by a method accepting a String[] for argument. This would be true of public static void main(String[] args), as well as the entry points for both the XJC and the Schemagen tools.

Returns:

an array holding all arguments in this ArgumentBuilder.

withFlag

public ArgumentBuilder withFlag(boolean addFlag,
                                String flag)

Adds a flag on the form -someflag to the list of arguments contained within this ArgumentBuilder. If the flag argument does not start with a dash ('-'), one will be prepended.

Typical usage:

     argumentBuilder
      .withFlag(someBooleanParameter, "foobar")
      .withFlag(someOtherBooleanParameter, "gnat")
      .withFlag(someThirdBooleanParameter, "gnu")
      ....
 

Parameters:

addFlag - if true, the flag will be added to the underlying list of arguments within this ArgumentBuilder.

flag - The flag/argument to add. The flag must be a complete word, implying it cannot contain whitespace.

Returns:

This ArgumentBuilder, for chaining.

withNamedArgument

public ArgumentBuilder withNamedArgument(boolean addNamedArgument,
                                         String name,
                                         String value)

Adds a name and an argument on the form -name value to the list of arguments contained within this ArgumentBuilder. The two parts will yield 2 elements in the underlying argument list. If the name argument does not start with a dash ('-'), one will be prepended.

Typical usage:

     // These values should be calculated as part of the business logic
     final boolean addFooBar = true;
     final boolean addGnat = true;
     final boolean addGnu = false;

     // Add all relevant arguments
     argumentBuilder
      .withNamedArgument(addFooBar, "foobar", "foobarValue")
      .withNamedArgument(addGnat, "-gnat", "gnatValue")
      .withNamedArgument(addGnu, "gnu", "gnuValue")
      ....
 

Parameters:

addNamedArgument - if true, the named argument (name and value) will be added to the underlying list of arguments within this ArgumentBuilder.

name - The name of the namedArgument to add. Cannot be empty.

value - The value of the namedArgument to add.

Returns:

This ArgumentBuilder, for chaining.

withNamedArgument

public ArgumentBuilder withNamedArgument(String name,
                                         String value)

Convenience form for the withNamedArgument method, where a named argument is only added if the value is non-null and non-empty after trimming.

Parameters:

name - The name of the namedArgument to add. Cannot be empty.

value - The value of the namedArgument to add.

Returns:

This ArgumentBuilder, for chaining.

withNamedArgument(boolean, String, String)

withPreCompiledArguments

public ArgumentBuilder withPreCompiledArguments(List<String> preCompiledArguments)

Adds the supplied pre-compiled arguments in the same order as they were given.

Parameters:

preCompiledArguments - A non-null List holding pre-compiled arguments.

Returns:

This ArgumentBuilder, for chaining.
