构造方法摘要

WildcardBinding(ReferenceBinding genericType, int rank, TypeBinding bound, TypeBinding[] otherBounds, int boundKind, LookupEnvironment environment)
When unbound, the bound denotes the corresponding type variable (so as to retrieve its bound lazily)

构造方法详细信息

WildcardBinding

public WildcardBinding(ReferenceBinding genericType,
                       int rank,
                       TypeBinding bound,
                       TypeBinding[] otherBounds,
                       int boundKind,
                       LookupEnvironment environment)

When unbound, the bound denotes the corresponding type variable (so as to retrieve its bound lazily)

方法详细信息

kind

public int kind()

覆盖：

boundCheck

public boolean boundCheck(TypeBinding argumentType)

Returns true if the argument type satisfies the wildcard bound(s)

canBeInstantiated

public boolean canBeInstantiated()

从类 ReferenceBinding 复制的描述

Answer true if the receiver can be instantiated

覆盖：

类 ReferenceBinding 中的 canBeInstantiated

另请参见：

ReferenceBinding.canBeInstantiated()

collectMissingTypes

public List collectMissingTypes(List missingTypes)

从类 TypeBinding 复制的描述

Iterate through the type components to collect instances of leaf missing types

覆盖：

类 TypeBinding 中的 collectMissingTypes

返回：
