public ElementSelector()

方法详细资料

toHumanReadableString

public abstract java.lang.String toHumanReadableString()

equals

public abstract boolean equals(java.lang.Object obj)

Must be implemented in a way so that this element can be distinguished from the other ones.

覆盖:

equals 在类中 java.lang.Object

参数:

obj - The object to check equality against.

返回:

true is the given object equals this one, otherwise false.

hashCode

public abstract int hashCode()

Make sure to implement this properly. If two elements are equal, their hash code must be equal as well. However, it is absolutely okay if two unequal elements return the same hash code. A simple implementation could just return 0.

覆盖:

hashCode 在类中 java.lang.Object

返回:

The hash code of this element.

toString

public final java.lang.String toString()

The string representation will only be used to print readable property paths for debug purposes.

覆盖:

toString 在类中 java.lang.Object

返回:

A string representation of this element for debug purposes.
