Method Details

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

targetHeight

public Integer targetHeight()

Gets the constraint on the target height for the thumbnail.

Returns:

The target height in pixels, or null if no constraint is set.

targetWidth

public Integer targetWidth()

Gets the constraint on the target width for the thumbnail.

Returns:

The target width in pixels, or null if no constraint is set.

toCanonicalRepresentation

public String toCanonicalRepresentation()

Gets the canonical string representation of this constraints set. This is compatible with equals, i.e. two constraints sets that are Object.equals(Object) have the same canonical representation. The canonical string representation can be parsed by ofCanonicalRepresentation(String).

Returns:

The canonical representation.

toString

public String toString()

Overrides:

toString in class Object

builder

public static ImageThumbnailGeneratorConstraints.Builder builder()

Creates a new builder for ImageThumbnailGeneratorConstraints.

Returns:

The new builder.

none

public static ImageThumbnailGeneratorConstraints none()

Gets a ImageThumbnailGeneratorConstraints object with no constraints.

Returns:

An object representing no constraints.

ofCanonicalRepresentation

public static ImageThumbnailGeneratorConstraints ofCanonicalRepresentation(String canonicalRepresentation)

Parses a canonical representation of constraints into a ImageThumbnailGeneratorConstraints object.

Parameters:

canonicalRepresentation - The canonical representation.

Returns:

The constraints object, or none() if the string is empty, or null if the string is or null.

Throws:

IllegalArgumentException - If the canonical representation is invalid.

ofCanonicalRepresentationOrNull

public static ImageThumbnailGeneratorConstraints ofCanonicalRepresentationOrNull(String canonicalRepresentation)

Parses a canonical representation of constraints into a ImageThumbnailGeneratorConstraints object.

Parameters:

canonicalRepresentation - The canonical representation.

Returns:

The constraints object, or null if the canonical representation is invalid.
