DrawCacheModifier

Kotlin |Java

interface DrawCacheModifier : DrawModifier

androidx.compose.ui.draw.DrawCacheModifier

DrawModifier implementation that supports building a cache of objects to be referenced across draw calls

Summary

Public methods
abstract Unit	`onBuildCache(size: Size, density: Density)` Callback invoked to re-build objects to be re-used across draw calls.

Inherited functions

From class Element

`Boolean`	`all(predicate: (Modifier.Element) -> Boolean)` Returns `true` if predicate returns true for all Elements in this Modifier or if this Modifier contains no Elements.
`Boolean`	`any(predicate: (Modifier.Element) -> Boolean)` Returns `true` if predicate returns true for any Element in this Modifier.
`R`	`foldIn(initial: R, operation: (R, Modifier.Element) -> R)` Accumulates a value starting with initial and applying operation to the current value and each element from outside in. Elements wrap one another in a chain from left to right; an Element that appears to the left of another in a `+` expression or in operation's parameter order affects all of the elements that appear after it. foldIn may be used to accumulate a value starting from the parent or head of the modifier chain to the final wrapped child.
`R`	`foldOut(initial: R, operation: (Modifier.Element, R) -> R)` Accumulates a value starting with initial and applying operation to the current value and each element from inside out. Elements wrap one another in a chain from left to right; an Element that appears to the left of another in a `+` expression or in operation's parameter order affects all of the elements that appear after it. foldOut may be used to accumulate a value starting from the child or tail of the modifier chain up to the parent or head of the chain.

Modifier

then(other: Modifier)

Concatenates this modifier with another.

Returns a Modifier representing this modifier followed by other in sequence.

Inherited extension functions

From androidx.compose.foundation.layout

Modifier	`Modifier.absoluteOffset(x: Dp = 0.dp, y: Dp = 0.dp)` Offset the content by (x dp, y dp).
Modifier	`Modifier.absoluteOffset(offset: Density.() -> IntOffset)` Offset the content by offset px.
Modifier	`Modifier.absoluteOffsetPx(x: State<Float> = mutableStateOf(0f), y: State<Float> = mutableStateOf(0f))`
Modifier	`Modifier.absolutePadding(left: Dp = 0.dp, top: Dp = 0.dp, right: Dp = 0.dp, bottom: Dp = 0.dp)` Apply additional space along each edge of the content in Dp: left, top, right and bottom.
Modifier	`Modifier.aspectRatio(@FloatRange(0.0, 3.4E38, false) ratio: Float, matchHeightConstraintsFirst: Boolean = false)` Attempts to size the content to match a specified aspect ratio by trying to match one of the incoming constraints in the following order: Constraints.maxWidth, Constraints.maxHeight, Constraints.minWidth, Constraints.minHeight if matchHeightConstraintsFirst is `false` (which is the default), or Constraints.maxHeight, Constraints.maxWidth, Constraints.minHeight, Constraints.minWidth if matchHeightConstraintsFirst is `true`.
Modifier	`Modifier.defaultMinSizeConstraints(minWidth: Dp = Dp.Unspecified, minHeight: Dp = Dp.Unspecified)` Constrain the size of the wrapped layout only when it would be otherwise unconstrained: the minWidth and minHeight constraints are only applied when the incoming corresponding constraint is `0`.
Modifier	`Modifier.fillMaxHeight(@FloatRange(0.0, 1.0) fraction: Float = 1f)` Have the content fill (possibly only partially) the Constraints.maxHeight of the incoming measurement constraints, by setting the minimum height and the maximum height to be equal to the maximum height multiplied by fraction.
Modifier	`Modifier.fillMaxSize(@FloatRange(0.0, 1.0) fraction: Float = 1f)` Have the content fill (possibly only partially) the Constraints.maxWidth and Constraints.maxHeight of the incoming measurement constraints, by setting the minimum width and the maximum width to be equal to the maximum width multiplied by fraction, as well as the minimum height and the maximum height to be equal to the maximum height multiplied by fraction.
Modifier	`Modifier.fillMaxWidth(@FloatRange(0.0, 1.0) fraction: Float = 1f)` Have the content fill (possibly only partially) the Constraints.maxWidth of the incoming measurement constraints, by setting the minimum width and the maximum width to be equal to the maximum width multiplied by fraction.
Modifier	`Modifier.height(height: Dp)` Declare the height of the content to be exactly heightdp.
Modifier	`Modifier.heightIn(min: Dp = Dp.Unspecified, max: Dp = Dp.Unspecified)` Constrain the height of the content to be between mindp and maxdp.
Modifier	`Modifier.offset(x: Dp = 0.dp, y: Dp = 0.dp)` Offset the content by
