Method Detail

omitNullValues

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper omitNullValues()

Configures the MoreObjects.ToStringHelper so toString() will ignore properties with null value. The order of calling this method, relative to the add()/addValue() methods, is not significant.

Since:

18.0 (since 12.0 as Objects.ToStringHelper.omitNullValues()).

add

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper add(String name,
                                      @CheckForNull
                                      Object value)

Adds a name/value pair to the formatted output in name=value format. If value is null, the string "null" is used, unless omitNullValues() is called, in which case this name/value pair will not be added.

add

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper add(String name,
                                      boolean value)

Adds a name/value pair to the formatted output in name=value format.

Since:

18.0 (since 11.0 as Objects.ToStringHelper.add()).

add

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper add(String name,
                                      char value)

Adds a name/value pair to the formatted output in name=value format.

add

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper add(String name,
                                      double value)

Adds a name/value pair to the formatted output in name=value format.

Since:

Adds a name/value pair to the formatted output in name=value format.

Since:

18.0 (since 11.0 as Objects.ToStringHelper.add()).

addValue

@CanIgnoreReturnValue

                                           Object value)

Adds an unnamed value to the formatted output.

It is strongly encouraged to use add(String, Object) instead and give value a readable name.

addValue

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper addValue(boolean value)

Adds an unnamed value to the formatted output.

It is strongly encouraged to use add(String, boolean) instead and give value a readable name.

Since:

18.0 (since 11.0 as Objects.ToStringHelper.addValue()).

addValue

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper addValue(char value)

Adds an unnamed value to the formatted output.

It is strongly encouraged to use add(String, char) instead and give value a readable name.

Since:

18.0 (since 11.0 as Objects.ToStringHelper.addValue()).

addValue

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper addValue(double value)

Adds an unnamed value to the formatted output.

It is strongly encouraged to use add(String, double) instead and give value a readable name.

Since:

18.0 (since 11.0 as Objects.ToStringHelper.addValue()).

addValue

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper addValue(float value)

Adds an unnamed value to the formatted output.

It is strongly encouraged to use add(String, float) instead and give value a readable name.

addValue

@CanIgnoreReturnValue
public MoreObjects.ToStringHelper addValue(long value)

Adds an unnamed value to the formatted output.

It is strongly encouraged to use add(String, long) instead and give value a readable name.

Since:

18.0 (since 11.0 as Objects.ToStringHelper.addValue()).

toString

public String toString()

Returns a string in the format specified by MoreObjects.toStringHelper(Object).

After calling this method, you can keep adding more properties to later call toString() again and get a more complete representation of the same object; but properties cannot be removed, so this only allows limited reuse of the helper instance. The helper allows duplication of properties (multiple name/value pairs with the same name can be added).

Overrides:

toString in class Object

Returns:

a string representation of the object.
